Dames Point Bridge by Doubtful-Della Dames Point Bridge by Doubtful-Della
(also known as the "Napoleon Bonaparte Broward Bridge" or "Dame Point Bridge")
Jacksonville, FL

America's longest cable-stayed bridge is two miles long, and 175 feet above the main channel of the river. The central span of the bridge is 1300 feet between the two towers which are 471 feet above the waterline at the top. The tower verticals are 7.25 feet thick and 35 feet wide at road level and 15 feet wide at the pinnacle. Dames Point's foundations extend roughly 80 feet beneath the surface of the St. John's River. The dredged channel underneath the bridge is 38 feet deep at high tide.

Dames Point Bridge carries six lanes of traffic on a deck 106 feet wide.

The concrete and steel deck is suspended by 168 steel cables which extend from the towers and connect to the edge girder of the span at 35 foot intervals. The cables consist of steel cable sheathed within steel pipe. The longest cable is 720 feet long, the shortest 65. Twenty-one miles of steel cables are used overall. Over 94,000 cubic yards of concrete were used.

Superlatives and Firsts
The Dames Point Bridge is the longest concrete cable-stayed bridge in the United States. It was the second cable-stayed bridge to be built in Florida (Tampa Bay's Sunshine Skyway was completed in 1984). It was the only bridge in the United States to feature the harp (parallel) stay arrangement on two vertical planes (Until the completion of the Sidney Lanier Bridge in Brunswick, Georgia in 2003), a design which rivals suspension bridges for strength and beauty. A concrete pouring milestone was set during the construction of the nothern pier foundation, as almost 19,000 cubic yards of concrete was continuously poured for 47 straight hours.

When I was a wee one, I called it the "Bowtie Bridge". I actually sometimes catch myself still calling it that. :)

Awesome shot, great composition, the structure in the middle looks like a bow tie, and the eyes are drawn to it by the cable.s

I was so unprepaired for this shot. We were trying to find something in Jacksonville, and all of the sudden we were like, what is that? Is that a bridge? WHERE'S MY CAMERA! Good thing I had it. I snapped a few shots and then later realized there was a reflection in the windshield from our paperwork. I was so mad. Thankfully this shot was reflectionless
